Technical field
The utility model relates to a kind of drying box, especially relates to the logical nitrogen double-purpose drying box of a kind of air blast, mainly uses drying and water analysis process in the coal testing process.
Background technology
At present, check and accept the field in the coal quality inspection, electrically heated drying box is generally used for the drying of coal or the test process of moisture in coal, and the major part that coal experiment laboratory uses is air dry oven, but for brown coal, because its reactivity is stronger, easily produce oxidation during heating, native land man correlation standard, the drying of brown coal and moisture measurement should adopt logical nitrogen dry, namely pass into nitrogen in drying box, and should be able to guarantee simultaneously that temperature is controlled and the requirement of rate of ventilation.For this reason, occurred special-purpose logical nitrogen drying box on Vehicles Collected from Market, but in order to economize on gas, it is less that its build designs usually, the brown coal drying that can only be used for little quality uses, and other coals that need to use dry run still need adopt general air dry oven for the laboratory.
In sum, the function that only has forced air drying that existing drying box for the coal testing process has, the function that only has logical nitrogen drying that has, cause thus having brought limitation to the use of this kind equipment, will purchase simultaneously logical nitrogen drying box and air dry oven so usually need to carry out the laboratory of brown coal analysis, to satisfy work requirements, this has just increased the input of equipment and the input in place, reduce the utilization rate of equipment, reduced to a certain extent the utilization rate of resource.
The utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and a kind of reasonable in design is provided, and is easy to use, both had the air blast function, has again the logical nitrogen double-purpose drying box of air blast of logical nitrogen function.
the technical scheme in the invention for solving the above technical problem is: the design feature of the logical nitrogen double-purpose drying box of this air blast is: comprise nitrogen cylinder, pressure-reducing valve, gas flowmeter, coral lattice plate type heat exchanger, the loading container, drying box body, appendix, air inlet pipe and escape pipe, described coral lattice plate type heat exchanger comprises heat exchange coil and pedestal, described heat exchange coil is fixed on pedestal, described pedestal and loading container are installed in drying box body, described pressure-reducing valve is arranged on nitrogen cylinder, one end of described appendix is connected on pressure-reducing valve, the other end of this appendix is connected on gas flowmeter, one end of described air inlet pipe is connected on gas flowmeter, the other end of this air inlet pipe is connected to an end of heat exchange coil, one end of described escape pipe is connected to the other end of heat exchange coil, the other end of this escape pipe is connected on the loading container.
As preferably, pedestal described in the utility model comprises framework and several reinforcement, and described reinforcement all is fixed in framework.
As preferably, loading container described in the utility model is box like structure.
As preferably, appendix described in the utility model, air inlet pipe and escape pipe are hose construction.
As preferably, heat exchange coil described in the utility model is stainless steel.
As preferably, framework described in the utility model and reinforcement are solid bar construction.
the utility model compared with prior art, have the following advantages and effect: simple in structure, reasonable in design, easy to use, both had the air blast function, has again logical nitrogen function, reduced the input amount of equipment, improved the utilization rate of equipment, can effectively use in drying and water analysis process that coal detects, when needs detect brown coal, brown coal to be detected are placed in the loading container, the nitrogen that is arranged in nitrogen cylinder passes through nitrogen cylinder successively, pressure-reducing valve, appendix, gas flowmeter, air inlet pipe, coral lattice plate type heat exchanger and escape pipe, finally enter in the loading container and protect brown coal, meanwhile, after these nitrogen for the protection of brown coal have passed through the preheating of coral lattice plate type heat exchangers, be conducive to improve the accuracy that brown coal detect.When detection need not the coal of logical nitrogen, only need close pressure-reducing valve and get final product.
The utility model can satisfy nitrogen flow fully and control and temperature controlled requirement according to the test of carrying out in the laboratory.Loading container in the utility model can be changed at any time, to adapt to the requirement of different coal sample amounts, saves nitrogen use level.The utility model can be on the basis of existing air dry oven, interpolation through simple structure, can realize the function of the logical nitrogen double-purpose of air blast, for the interpolation cost increase that builds seldom, only air inclusion flowmeter, coral lattice plate type heat exchanger, loading container and some tube connectors, can transform easily for existing air dry oven, one or more coral lattice plate is all arranged in current common drying box, carry out dry sample in order to put, replace to coral lattice plate type heat exchanger and get final product therefore only need to have now coral lattice plate.The utility model for the drying box cost increase of new production also seldom.
